Recently, SFTP upload and download should be configured in the project. After the environment is configured, the connection will report an error.

The error information is as follows:

paramiko.ssh_exception.SSHException: Error reading SSH protocol banner

Solution 1:

Set banner_ Timeout property value

You can change the transport.py under the paramiko Library in the site packages source file. The transport code is as follows:

 class Transport(threading.Thread, ClosingContextManager):
        self.banner_timeout = 15
        # how long (seconds) to wait for the handshake to finish after SSH

15 can be changed to 30

Solution 2:

Pay attention to check your host, port, username, password and other information, as well as upload or download directory path!
